Last change on this file since 5802 was 3366, checked in by rgrieder, 15 years ago

Derived all singletons implemented in a usual manner from orxonox::Singleton<T>.
This resolves inconsistencies with the singletonPtr_s variable in case of exceptions (asserts were being triggered then).
And while at it replaced singletonRef_s with singletonPtr_s for it to be less misleading (as fabian has already pointed out).
